SPECIFICATION forming part of Letters Patent No. 614,174, dated November15, 1898. Application filed June 25,1898. Serial No. 684,198. (Nomodel.)

with the frames and driving-gears of bicycles of the present ordinarytypes in which the rear road=wheel is the driven wheel and power istransmittedto it from pedal-cranks and shafts of cranks and shaftsbetween the rear and front wheel.

The invention will be described by the aid of the accompanying drawings.

Figure 1 is a side elevation, and Fig; 2 an end view, in which the poweris transmitted from the pedal crank shaft or shafts to the rear wheelthrough chain-and-sprocket gearin g.

Referring to the drawings,- the power is transmitted from thecrank-shaft a to the road-wheel W by a sprocket-wheel e on the shaft a,a sprocket-wheel i on the Wheel-hub of W, and a chain f, as usual.According to this invention a casing integral with the frame of thecycle, both at the crank-axle part and the part at the rear road-wheelaxle, is carried around the front sprocket-Wheel, outside the chain,between this part and the back sprocket-wheel, both at the top andbottom run thereof, and around the rear sprocketwheel, all of whichparts are integral with each other and with the frame of the cycle, bothat the front and back, and form part thereof.

The construction according to this invention is shown in the drawings.The sprocketwheel c is inclosed within a casing e at the front, which iscast in one with the axle-box e and forms a part of it, while thereanwheel i is inclosed in a box-casing consisting of an inner half handan outer half, constituting a cap or cover 70. These two boxes or cases6 and 7c are connected together above and below by closed tubes ormembers g ,which are brazed to or equivalently secured in sockets e andform together an integral part of the frame of the bicycle, and theyalso serve as a casing or conduit through which the sprocketintegralportion of the whole bicycle-frame and takes all the strain to which thebicycle is subjected at this side. The frame of the bicycle runningbetween this axle-box and the will be of the usual type.

The box-cover k is secured to 70 by screws or bolts and a flange at 70as shown, so that it can be easily removed for gaining access to shaftof the wheel W is at this side of the machine secured in any knownsuitable way to the part 70. Access also is had to the front gear-box cby a plate 6 which is screwed or opening in the front side of same.

What is claimed in respect of the hereindescribed invention is- In abicycle-gearin g, in which the rear roadfront of it, front and rearsprocket-wheels c i and chain f, as described; a casing e extendingoutside and around the front driving sprocket-wheel, and integral withthe cranktending outside and around the rear driven sprocket-Wheel; andcasing-tubes g outside the upper and lower lengths of chain betweenthese forward and rear ca sing portions 6 and and intermediate partsforming together an integral portion of the frame of thecycle at oneside between the crank-axle and rear part of the frame, and taking allthe strains tially as set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
